A cable conveyor for underground engineering cable laying

Abstract

This utility model discloses a cable conveyor for underground cable laying, including a base plate on which the cable conveyor body is mounted; and several roller assemblies connected to the base plate via telescopic components. The distance between the roller assemblies and the base plate is adjusted by the telescopic components. This utility model has a simple structure. By cooperating with the base plate, telescopic components, and roller assemblies, and by adding rollers around the cable conveyor, the cable conveyor can move on temporary rails, facilitating efficient and continuous laying and reducing downtime for adjustments. During the laying phase, the rollers are pushed out using the telescopic frame, thereby locking the rollers onto the temporary rails and allowing them to move on the temporary rails. This ensures that the cable conveyor will not move due to cable dragging force, reducing displacement and positioning errors caused by dragging. Furthermore, the telescopic frame design allows the rollers to adapt to temporary rails of different gauges, and the rollers can be folded for normal use on conventional ground.

Description

Technical Field

[0001] This utility model relates to the field of underground engineering cable laying technology, specifically a cable conveyor for laying cables in underground engineering. Background Technology

[0002] In the early stages of underground engineering construction, temporary tracks are typically laid in advance to meet the needs of material transportation and equipment movement, and are then removed after the main structure is completed. Due to differences in site space conditions, transportation loads, and work processes, the gauge of the temporary tracks often varies, exhibiting diverse and non-standardized characteristics.

[0003] In the aforementioned temporary track environments, it is often necessary to simultaneously or subsequently lay power and communication cables. Such operations require a long-term, stable guiding and pulling path along the track to ensure the cables are laid safely and efficiently, while avoiding damage to the temporary track itself and surrounding facilities. Cable conveyors, as electromechanical devices used for laying power or communication cables, can work in conjunction with cable traction machines, hoists, and other supporting equipment to significantly improve construction efficiency and reduce labor costs. They are widely used in urban power grid upgrades and long-distance, large-section cable laying scenarios. They possess advantages such as high thrust, small size, light weight, and convenient operation, making them particularly suitable for complex conditions such as tunnels, ductwork, and direct burial.

[0004] However, existing cable conveying equipment has significant limitations when applied to temporary tracks with different gauges. For example, the "Wireless Controllable Intelligent Cable Laying Conveyor" application (CN202322864407.6), while possessing functions such as wireless control, tracked movement, and cable length feedback, uses a tracked ground-based structure and lacks a self-guiding walking mechanism compatible with temporary tracks. The equipment cannot operate continuously and stably along the track, requiring frequent manual handling, positioning, and alignment when switching between track and ground sections. Especially during long-distance laying, the machine needs to be stopped and moved approximately every 50 meters, disrupting the construction cycle, significantly reducing work efficiency, and increasing the labor intensity and number of on-site workers. Furthermore, due to varying track gauges in different sections, traditional conveyors struggle to quickly adapt to multiple gauge changes and lack flexible wheel gauge adjustment capabilities, further limiting their applicability in variable underground construction environments. Therefore, this paper proposes a cable conveyor for underground engineering cable laying. Utility Model Content

[0005] The purpose of this utility model is to provide a cable conveyor for laying cables in underground engineering, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable conveyor for underground engineering cable laying, comprising... The base plate, on which the cable conveyor body is mounted; and Several roller assemblies are connected to the base plate via telescopic components, and the distance between the roller assemblies and the base plate is adjusted by the telescopic components.

[0007] As a further embodiment of this utility model: the telescopic component includes: A support plate is disposed on a base plate, and a strip groove is formed on the side of the support plate away from the base plate; A lead screw, on which a threaded block is mounted, is also housed within a slot; and The telescopic frame has its ends near the support plate rotatably connected to the strip groove and the threaded block, respectively.

[0008] As a further embodiment of this utility model: a plurality of sliding rods are installed in the strip groove along the length of the strip groove, and the plurality of sliding rods are in sliding engagement with the threaded block.

[0009] As a further embodiment of this utility model: a fixing block is installed at the end of the slide rod, and a control block is installed on the fixing block. One end of the control block is connected to the lead screw, and a groove is provided at the end of the control block away from the lead screw to assist the operator in rotating the control block.

[0010] As a further embodiment of this utility model: the roller assembly includes: A fixed plate is connected to the end of the telescopic frame away from the support plate; and A folding roller is connected to a mounting plate and a fixed plate, and a locking element is installed on the folding roller, which is also equipped with a control foot pedal.

[0011] As a further embodiment of this utility model: the number of telescopic components is four, and the four telescopic components are respectively arranged on opposite sides of the base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the cooperation of the base plate, telescopic components, and roller components, adds rollers around the cable conveyor, enabling the cable conveyor to move on temporary rails. This facilitates efficient and continuous laying, reducing downtime for adjustments. During the laying phase, the telescopic frame pushes out the rollers, causing them to engage with and move on the temporary rails. This ensures that the cable conveyor will not move due to cable dragging force, reducing displacement and positioning errors caused by dragging. Furthermore, the design of the telescopic frame allows the rollers to adapt to temporary rails of different gauges, and the rollers can be folded for normal use on conventional ground.

[0013] 2. This utility model reduces the reliance on specialized traction or guidance personnel by utilizing the self-guiding and positioning capabilities of the rollers. This reduces the number of on-site personnel required during the initial assembly and deployment phases, while also reducing downtime and rework caused by cable dragging and fluctuations. This improves the time utilization rate of continuous laying, reduces equipment downtime and maintenance frequency, and enhances laying efficiency and quality. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 In this embodiment of the utility model, a cable conveyor for laying cables in underground engineering includes... Base plate 1, on which cable conveyor body 2 is mounted; and Several roller assemblies are connected to the base plate 1 via telescopic components, and the roller assemblies adjust the distance between themselves and the base plate 1 via the telescopic components.

[0018] Specifically, the upper surface of the base plate 1 is equipped with a cable conveyor body 2 for transporting cables, and there are four telescopic components. The four telescopic components are respectively set on opposite sides of the base plate 1. The four telescopic components are connected to temporary tracks in pairs. This ensures that the roller components connected to the telescopic components fall on the corresponding temporary tracks. When the track gauge between the temporary tracks is inconsistent with the distance between the two roller components, the telescopic components control the corresponding roller components to accurately fall into the corresponding temporary tracks, thereby ensuring that the conveyor can run smoothly on temporary tracks with different track gauges and ensuring the efficiency of cable laying.

[0019] Please see Figure 3-4 In one embodiment, preferably, the telescopic component includes: A support plate 3 is mounted on a base plate 1, and a strip groove 4 is provided on the side of the support plate 3 away from the base plate 1. The lead screw 5, on which a threaded block 6 is mounted, is also disposed inside the slot 4; and The telescopic frame 7 is rotatably connected to the strip groove 4 and the threaded block 6 at the end near the support plate 3.

[0020] Specifically, the strip groove 4 is a groove with openings on both sides, penetrating the upper end face of the support plate 3. The lead screw 5 is arranged along the length of the strip groove 4. Several sliding rods 11 are installed inside the strip groove 4, arranged along the length of the strip groove 4. The sliding rods 11 are all slidably engaged with the threaded block 6, and the sliding rods 11 are fixedly connected to the inner wall of the strip groove 4. The threaded block 6 and the lead screw 5 are connected by threads. The telescopic frame 7 has two ends, each end containing four ends, of which the four ends located inside the strip groove 4 are... Two are connected to the threaded block 6 and the strip groove 4 respectively. Specifically, one end is hinged to the inner wall of the strip groove 4 and its position is fixed; the other end is hinged to the threaded block 6. The two ends are arranged in a cross pattern. When the screw 5 is rotated, the threaded block 6 is driven to move up and down along the length of the slide rod 11. Since the position of one end is fixed, while the other end moves up and down with the threaded block 6, the cross angle between the two ends changes accordingly, thereby driving the other end of the telescopic frame 7 to extend or retract, thus realizing the adjustment of the position of the roller assembly.

[0021] Please see Figure 3-4In one embodiment, preferably, a fixing block is installed at the end of the slide bar 11, and a control block 12 is installed on the fixing block. One end of the control block 12 is connected to the lead screw 5, and a groove is provided at the end of the control block 12 away from the lead screw 5 to assist the operator in rotating the control block 12. Furthermore, a rotating hole is provided on the fixing block, and the part of the rotating hole that contacts the control block 12 is tightly fitted, and the two are in a relatively locked state. When an external force is applied to the control block 12, the lead screw 5 can rotate relative to the rotating hole. The shape of the groove is not limited. In this embodiment, preferably, the shape of the groove is hexagonal, which is used in conjunction with a hexagonal wrench to realize the rotation of the control block 12.

[0022] Please see Figure 3 In one embodiment, preferably, the roller assembly includes: Fixed plate 8 is connected to the end of telescopic frame 7 away from support plate 3; and A folding roller 10 is connected to a fixed plate 8 via a mounting plate 9. A locking element 13 is installed on the folding roller 10, and a control foot pedal is installed on the locking element 13.

[0023] Specifically, the four ends of the fixed plate 8 are hinged to the other end of the telescopic frame 7 and fixedly connected to the mounting plate 9. The mounting plate 9 provides support for the folding roller 10. The folding roller 10 is provided with a locking member 13, which can contact the outer surface of the folding roller 10 to lock it and prevent rotation. The locking member 13 is equipped with a control foot pedal, which allows the operator to control the position of the locking member 13 by operating the foot pedal to lock or release it.

[0024] The working principle and usage process of this utility model are as follows: In use, the base plate 1 and the cable conveyor body 2 are placed between two temporary rails. Then, the connecting rod on the folding roller 10 is controlled by the locking piece 13 to lower the folding roller 10. Then, the control block 12 is rotated by the hexagonal tool. The control block 12 drives the lead screw 5 in the strip groove 4 to rotate. The threaded block 6 moves linearly on the lead screw 5 through the action of the thread. Through the linear movement of the threaded block 6, one side of the telescopic frame 7 is moved, thereby adjusting the angle of the internal rods of the telescopic frame 7. As the threaded block 6 slides downward, the angle of the internal rods of the telescopic frame 7 becomes smaller, thereby increasing the linear distance of the telescopic frame 7. When the threaded block 6 is at the bottom of the lead screw 5, the telescopic frame 7 is fully extended. At this time, the four folding rollers 10 are locked on the temporary rails to ensure that the base plate 1 and the cable conveyor body 2 will not move due to the drag force of the cable when pulling the cable. The base plate 1 and the cable conveyor body 2 move on the rails through the folding rollers 10, and the cable is laid through the movement of the folding rollers 10.

Those skilled in the art should consider the specification as a whole.
